Simple Stirling 1 performance with and without regenerator

I’ve tried a variety of regenerators on the Simple Stirling 1 engine and the one shown in the photo is simple to make and performs as well as or better than all of the other ones I’ve tried. The test results on the engine with the original displacer and with the modified displacer containing the […]

Simple Stirling 1 Engine Materials List

The bill of material for the Simple Stirling 1 Engine is now available. Together with the 3D model, the part drawings, and assembly drawings, you now should have sufficient documentation for building the engine. I believe I’ve covered every single part including nuts, machine screws, and washers.

Simple Stirling 1 Plans and Assembly drawings

I have added color to the 3D CAD model. You can see it compared above with the physical prototype. There are a few difference between the two—the four support rods on the prototype are about 1.5 inches longer than on the plans. You might also notice I have the crankshaft set 180° from the CAD […]

The Simple Stirling 1 Plans are done !

The plans all drawn up. You can see a 3D pdf model that gives you the ability to look at every single part from any angle. If you haven’t used this Adobe 3D view make sure to try both mouse buttons and the mouse wheel for navigating the drawing. There is a directory tree that […]

Maker Faire 2008

From 2008_05_05 Ma…     I want to thank all the people who stopped by to see the solar power Stirling engine in operation. I appreciate the questions, comments and interest in the engine. I regret that I was unable to offer a better response to those that asked about the efficiency. I simply cannot […]

Torque and Power measurement of low-speed, low-power engine

I needed to measure the torque and power output of my Stirling engine so that I could compare it with the simulation. The engine currently spins up to 70 RPM and has torque levels up to around 2 in-lbs. My first attempt at a design to measure torque was easy to make and gave satisfactory […]

Engine model 3d is up and running!

Engine model 3d has actually been running for over a week now, but I finally am taking time to start getting this website up-to-date. You can see more photos in the photo pages. I’m in the process of performance testing the engine to see how closely its power output agree with my simulation. There are […]
